Title: Device for generating rotary oscillations for ring-laser gyroscopes
Inventor: HOFFMANN HARTMUT DIPL ING
IPC: G01C19/70
Filed: 1985-12-13
Abstract: To suppress the so-called lock-in effect, a torsional oscillation is applied to ring-laser gyroscopes. For this purpose, a so-called dither joint is used on which a laser block 15 is mounted and which oscillates about the Z axis. This dither joint consists, for example, of two torsional vibrators 1 and 2 which in each case exhibit a hub 3, 4. On these hubs, radially directed webs 7-12 are arranged which are in each case connected at their outer ends via rings 13, 14. The rings are braced against one another and produce a frictionally engaged force link between the joint and a block flange 35 of the laser block. It is known that the laser block is produced of a material having a very low temperature expansion coefficient. So that no excessive stresses are generated in the laser block during temperature fluctuations with the comparatively relatively high coefficient of temperature expansion of the joint, a length-compensating element, for example a disc washer 34 or a compensating disc is placed underneath the screw connection of the two rings 13, 14. To avoid stresses in the webs, the two hubs 3, 4 are connected to one another via a diaphragm 21. Advantages of this arrangement:   - axial clamping of the laser block via the rings 13, 14, as a result of which the webs 7-12 are relieved, - anti-rotation locking of the two hubs 3, 4 by diaphragm 21 and as a result additional temperature compensation in the axial direction.   - Compensation of the ...

Patent DE-3603630-A1 (DE)
Title: Control arrangement for at least two hydraulic consumers fed by at least one pump
Inventor: KRETH NORBERT DR ING
IPC: F15B13/042
Filed: 1986-02-06
Abstract: A pump supplies several consumers with pressure medium via one directional control valve each, a pressure balance for regulating the valve volumetric flow independently of the load being provided between each branch line, branching off from the pump delivery line, and the directional control valve. In a pressure-regulating valve, a control pressure is produced from the differential pressure of the pump pressure and the maximum respective consumer pressure. The control pressure acts on all pilot-control devices which are provided for the hydraulic activation of the directional control valves. If there is insufficient pump delivery pressure, the control pressure to the pilot-control devices is reduced by the pressure-regulating valve, and a proportional reduction in volume at all consumers is achieved by means of the resulting stroke reduction at the directional control valves.

Title: Device for monitoring the content of expansion vessels and the like loaded with gas pressure
Inventor: SENGER MICHAEL DIPL ING
IPC: G01F23/00
Filed: 1986-04-24
Abstract: This invention relates to monitoring of the content of expansion vessels and the like loaded with gas pressure, such as, for example, in heating systems, for the purpose of indicating and/or controlling a liquid volume by an elastic means acting in a diaphragm-like manner in the expansion vessel, such as, for example, with a rubber bladder for separating and changing the volume present in the expansion vessel in the liquid space or gas space. According to the invention, there is arranged above the surface of the bladder or diaphragm a band or belt which is made of non-stretchable material and which, on the one hand, is fastened to the inner wall of the expansion vessel and, on the other hand, is guided out of the vessel. By the variation in length of the belt as a result of the expansion of the diaphragm or bladder in the expansion vessel, the liquid volume is indicated mechanically and/or electrically. The measured values can also be used for controlling the volumetric ratios in the expansion vessel.

Title: Patent facet and its production
Inventor: EMMEL WOLFGANG
IPC: G02C7/02
Filed: 1986-08-08
Abstract: Designation: Plastics spectacle lens for above average minus powers, in which the thickness in the edge region decreases for the purpose of reducing weight and on aesthetic grounds, and which is provided with a facet section in order to achieve an ornamental effect. Representation of the invention: Thick spectacle lenses having an edge thickness of 10-15 mm are thinned out at the edge in order to reduce the weight and to achieve an aesthetic impression, and are incipiently milled with different radii on the outer edge on the side facing the eye, in order to achieve an ornamental effect. Production of the facet lenses: The raw glass (blank) supplied is appropriately ground and polished to the required size and shape. These operations are conventional and generally known. The glass is now thinned out using a milling tool. It is possible to provide a facet section which is clean and extends in a uniformly rectilinear fashion, or else is discontinuously shaped. This handling of the lenses, which would otherwise be very heavy and have a ponderous effect produces a noteworthy reduction in weight and a substantially more aesthetic impression and a marked ornamental effect.

Title: Microfilm image-reading device with positional security of the film image
Inventor: BEHR KARL-GUENTHER
IPC: G03B21/11
Filed: 1986-11-06
Abstract: A microfilm image-reading device with a film carrier which is displaceable in the X and the Y direction and in which the microfiche is held between a support plate fixed to the film carrier and a removable cover plate is described. The film carrier is characterised on the one hand in that the cover plate is tiltable on its rear side about an axis and mechanical means are provided, which, in the case of a displacement of the film carrier for the purpose of microfilm changing into the foremost Y position, tilt the cover plate about this axis and thus automatically remove the cover plate from the support plate. On the other hand, the film carrier is characterised by an angle sheet which is mounted on its front crosspieces and which, with the cover plate raised, is raised under spring force into a stop position for the microfiche, but which, when the cover plate is lowered, is pressed down by the latter into its rest position again.

Title: Torsional vibration damper
Inventor: ANDRAE RAINER DIPL ING DR
IPC: F16F15/14
Filed: 1986-11-08
Abstract: A torsional vibration damper in which the hub ring 4 and the inertia ring 3 are connected by rubber spring units which are distributed uniformly over the circumference and vulcanised in. These units comprise first and second spring elements 1, 2 of columnar design which merge into one another at the outside and are spaced apart at the inside. The second spring elements are spring-loaded by the first spring elements and, when the torsional vibration damper is not rotating, exhibit a clearance at the outside with respect to the inner side of the inertia ring 3. At a desired speed of rotation, they come to rest immovably against the inner side of the inertia ring due to centrifugal force and, as a result, they act in parallel with the basic spring elements 6. <IMAGE>
Patent DE-3642091-A1 (DE)
Title: Friction clutch
Inventor: BRAUN SIEGFRIED
IPC: F16D43/21
Filed: 1986-12-10
Abstract: The invention relates to a friction clutch for gearboxes, intended, in particular, for installation in marine transmissions, and designed as a spring-loaded safety clutch. The friction clutch can additionally be equipped with a servo device. The friction clutch disclosed is distinguished from hitherto known designs by the fact that one or more longitudinally displaceable fitting members for axial force transmission and for rotary drive transmission are mounted between a pressure plate (9, 11) belonging to the second half of the clutch and supporting the friction element (16), on the one hand, and the spring (4) supported on the gear (2, 3) to be coupled, on the other hand, these fitting members being supported, on the one hand, on the spring and, on the other hand, on the pressure plate. The inventive design of the friction clutch makes it possible, particularly in the case of forward-reverse gearboxes with bevel gears, to install larger diaphragm springs and eliminates the inner disc carrier toothing and the space requirement for it. It is thereby possible to keep down the masses which have to be moved by the spring in the case of overloading, and the overall length is reduced. Together with larger spring diameters, rapid response of the clutch in the case of overloading is guaranteed and the wear of the hitherto customary disc toothing is now shifted to the inexpensive and easily replaced fitting pieces (Fig. 1). <IMAGE>

Title: Control arrangement for at least two hydraulic consumers fed by at least one pump
Inventor: KRETH NORBERT DR ING
IPC: F15B11/16
Filed: 1986-12-30
Abstract: A pump supplies a plurality of consumers with pressure medium via in each case one directional control valve, a pressure balance for load-independent separation of the pump delivery quantity being provided between each branch line, branching off from the pump delivery line, and the directional control valve. In a control-pressure device common to all pressure balances, a control pressure passed on to all pressure balances is generated. The control signal is generated in a pressure transducer, which is acted upon by the pump pressure and the consumer pressure which is highest in each case. This signal is supplied to an amplifier as the actual value, and the pressure-regulating valve is driven in accordance with the difference between desired and actual value.
